Hybrid Ceramic Bearing 608 of Steel Races+ZrO2/Si3N4 Balls For Ceramic Ginder Wheel
Description of Hybrid Ceramic Bearing 608:
1. Races can be chosen among GCr15 bearing steel, 440C stainless steel, high temperature resistant bearing steel, etc.,
2. Balls can be chosen among zirconia or silicon nitride ceramic balls, and their precision can reach G5 Grade.
Performance advantages of Hybrid Ceramic Bearing 608:
Non-magnetic, non-conductive, low noise, electrically insulated, non-locking at high speeds, resistant to dry friction, long life, cost effective and etc.
Main application of Ceramic Ginder Wheel fitted with Hybrid Ceramic Bearing 608:
Because of the high hardness of races and good properties of ceramic balls, the ceramic ginder wheel fitted with our Hybrid ceramic bearing 608 can be used in the bearings grinding machine.
